6 Claims.

This invention has to do with curtain fixtures of the type wherein theoutwardly spring-pressed heads at the ends of the fixture are equippedwith facing strips of rubber or other suitable material for frictionalengagement with the guides.

The object of the invention is to provide a facing strip which may bequickly and easily applied to or removed from the head and yet cannotcome loose or work out of position while in service.

In order that the invention may be readily understood, three differentforms of the same are presented herein, but it will of course beappreciated that such forms have been chosen primarily for the purposeof exemplil'lcation. and that the invention is susceptible of embodimentin still other structurally modified forms coming equally within thescope of the appended claims.

In the accompanying drawing:

Fig. 1 is a side view of a curtain lixture head equipped with areplaceable facing strip, in accordance with the invention;

Fig. 2 is a top view of the head;

Fig. 3 is a vertical section through the center of the head;

Fig. 4 is a horizontal section, taken on the line 4--4 of Fig. 3;

Fig. 5 is a vertical section through a modied head structure, showinganother form of the invention;

Fig. 6 is a horizontal section, taken on the line 6 6 of Fig. 5;

Fig. 7 is a vertical section through another modied head structure,showing still another form of the invention; and

Fig. 8 is a horizontal section, taken on the line B-8 of Fig. 7.

The head shown in Figs. 1 to 4 inclusive is made of sheet metal and isprovided with a sleeve portion I0 which is journaled on a stem II. Theouter portion I2 of the head is vertically elongated, tapers toward itsupper and lower ends,

is U-shaped in cross section throughout subfstantially its entirelength, and opens outwardly toward the guide against which the head isadapted to bear. The back I3, sides I4 and ends I5 of the outer portionI2 of the head are closed, and the ends I5 are provided with inturnedlips I 6 which are disposed iiush with the edges of the sides I4.

The head is equipped with a soft rubber facing strip Il which, insteadof being riveted or otherwise xedly secured in position, is removablyseated in the shallow trough-like pocket or recess present in, the outerportion I2 of the head. The

strip Il is somewhat longer than the head and is T-shaped in crosssection, with a center rib I8 and side flanges I9. When the strip Il, isin position the rib I8 iills up the recess in the head and abuts againstthe back I3 of the head throughout a substantial area and the sideflanges I9 abut against the outer edges of the sides I4 and ends I5,with the ends of the. strip projecting beyond the ends of the head. Therib I8 of the rubber strip is provided near its ends with L-shaped slots2U, into which the correspondingly shaped ends I5 and lips I6 of thehead are adapted to fit. The strip Il can be sprung into or out oflocked position in` the head by grasping the strip and bowing out thecenter of the same far enough to move the ends toward each other andallow the L-shaped slots 2Il to be drawn clear of the lips I6. After thestrip Il has been allowed to straighten out, however, into its normaloperating position, no force met with in service will ever dislodge it.The extreme ends 2| of the rib I8 beyond the ends I5 of the head provideexcellent bumpers for the head. To facilitate bowing or arching of thestrip Il in applying or removing it from the head, the rib I8 ispreferably provided with a notch 22 at the center of the strip, whichnotch allows the strip to be bent outwardly at its center without anydiiiiculty and at the same time provides needed clearance for the inneradjusting tip 23 of the stem I I. The anges I9 along the sides of thestrip Il give the latter somewhat greater width than the supportingmetal parts of the head, with the result that only the strip Il cancontact with the sides of the groove in the guide.

In the form of the invention which is illustrated in Figs. 5 and 6 theends of the head 24 are cut away and cross pins 25 are mounted in theside Walls 26 of the head adjacent the ends of the side walls. Therubber facing strip 2l which fits into the head is provided near itsends with curved slots 28 which afford, with the pinsl 25, connectionsbetween the facing strip and the head.

In the modification which is shown in Figs. 'l and 8, the ends 29 of thehead are turned inwardly vat an angle away from the ends of the sidewalls 29 and fit into correspondingly shaped slots 3D in the ends of therib 3| on the back of the facing strip 32.

I claim:

l. In a curtain iixture, a metal head, a rubber facing strip for thehead, and interlocking formations on the head and strip which normallyhold the strip in correct position relative to the head but permitremoval of the strip upon deformation of the latter.

2. In a curtain fixture, a metal head, a rubber facing strip for thehead, and oppositely facing L-shaped joint connections between the endsof the head and the ends of the strip which normally hold the strip incorrect position relative to the head but permit removal of the stripupon an arching of the latter intermediate said connections.

3. In a curtain fixture, a vertically elongated sheet metal head ofU-shaped cross section which opens toward the guide with which it isadapted to coact, and a rubber facing strip for the head having a rib atits back which fits Within the head and flanges at its sides which fitagainst the edges of the sides of the head, said head being providedinteriorly of the same with cross members which are spaced from the backof the head adjacent the ends of the latter, and said stripbeingprovided with slots in the rib portion thereof which intert with thecross members in such fashion as to block both endwise and outwardmovement of the strip bodily relative to the head.

4. In a curtain xture, a vertically elongated sheet metal head ofU-shaped cross section which is tapered toward its upper and lower endsand opens throughout a substantial part of its length toward the guideWith which it is adapted to coact, and a rubber facing strip for thehead having a rib at its back Which ts Within the head and flanges atits sides which t against and project beyond the edges of the sides ofthe head, said head being provided with inturned lips on its ends, andsaid strip being provided With L- shaped slots in the rib portionthereof Which intert With the lips and the ends of the head whereby toprevent both endwise and outward movement of the strip bodily relativeto the head.

5. In a curtain fixture, a head, a deformable contact member for thehead, and interlocking formations on the head and contact member whichnormally hold the latter in correct position relative to the head butpermit removal of the contact member upon deformation of the same.

6. A contact member for the head of a curtain xture, consisting of arubber strip which is provided adjacent its ends with oppositely facingL-shaped slots.
